    just picked up an rv016 to act as our main router (based on everyone's help here). we also have a WRT54G which i am configuring to work as just a wireless AP. there's also a SR224 switch involved.

    RV016: 192.168.1.1
    WRT54G: 192.168.1.2

    wired the rv016 into my box and configured the wan1 port with the settings from our isp (exactly as they were on the WRT54G, which was our main router previously). went into the WRT54G setup page, changed it from gateway to router, disabled the DHCP server.

    disconnected the internet from the WAN port of the WRT54G, and plugged it into the WAN1 port of the RV016. connected the two routers together via patch cable.

    at this point, you would think i should be good to go...right? nope. can see everything on the internal network just fine (file sharing works, can see all our broadband phone adapter web setup pages, EVERYTHING works fine on the inside) - cannot see out to the internet. according to the status logs, there are packets and traffic coming through the WAN port, but we cannot access any websites. even tried switching from WAN1 to WAN2 to see if perhaps it was a bad port...no luck. checked the firewall settings and access rules, and all appears to be set up correctly there as well.

    someone please help me here...i've been pulling my hair out all morning and i'm getting very frustrated. what am i missing?

    There is a "multiple subnets" feature which you need to enable and specify the 192.168.1.2 subnet in the setup page of RV016's web admin utility.

    crackers8199 LI Guru Member

    i'm not using multiple subnets at this point, though. why would i need to enable that?
     
  4. crackers8199

    crackers8199 LI Guru Member

    i cannot even find this "multiple subnets" feature anywhere in the setup page to try it...

    one other note - the problem seems to be that windows xp is not getting the dns servers. when i connect using the WRT54G as our main (and only) router, if i look at the connection properties in xp I can see the two DNS servers given to us by comcast. when connecting through the RV016, the only dns server listed is 192.168.1.1.

    not sure if this is causing the problem, but thought i'd pass that info along too...
     
  6. crackers8199

    crackers8199 LI Guru Member

    ok, now xp can see the dns servers, but still no internet connection...

    linksys tech support wants to replace the router, but i really have a hard time believing it is defective when there is traffic coming in and out of the WAN port...someone help, please! i dont want to send this back for a new one and have the exact same issue with the new one...

    are you one cable? if so try reboot the cablemodem.
     
  8. crackers8199

    crackers8199 LI Guru Member

    yeah, we're on cable but i don't have access to the modem to reboot it...there's one modem for the whole building. linksys seems to think it's defective, i'm on the phone with staples right now trying to arrange for a replacement - but if there's anything else i should be checking, please let me know.

    one other tidbit that makes me think now maybe it is defective - it doesn't seem to work if i even use the old router as the gateway and the rv016 as a router...i'm completely stumped.

    UPDATE:

    got it working when using the WRT54G as the gateway, RV016 in router mode (with RIP enabled), still unable to get it working with the rv016 as the gateway and the WRT54G in router mode.

    one thing i have noticed - these are the only two entries in the routing table for the rv016:

    Code:
    Destination IP Address  	Subnet Mask  	Default Gateway  	Hop Count  	Interface
    192.168.1.0	255.255.255.0	192.168.1.2	0	ixp0
    192.168.1.0	255.255.255.0	*	50	ixp0

    the new router came in from staples today to replace the one that linksys thought was defective...sure enough, same problem. i'm now even more confident that the router is NOT defective and that there's just some stupid issue here that i'm not seeing. anyone have any ideas?

    If you haven't rebooted your modem, it may be restricting internet access when it doesn't "see" the MAC address of the WRT54G. Clone the MAC if you can't reboot the modem and see what happens.
     
  13. crackers8199

    crackers8199 LI Guru Member

    tried that, with no luck - we also hooked up an older router we had laying around (from before the WRT54G was connected), and that one worked just fine (different mac address) - so that doesn't appear to be the issue either.

    I dont mean to insult your inteligence but you are using the correct WAN port on the RV016 yes?
     
  15. crackers8199

    crackers8199 LI Guru Member

    LOL, by all means please do insult my intelligence... :) any ideas at all, throw them to me...

    i know i'm probably missing something incredibly stupid like that, but can't see it because i'm getting so frustrated after three days of this.

    yes, i'm using the correct WAN port. i've also tried using WAN2, thinking perhaps there was a bad port...no luck. even tried turning on 7 WAN ports and using WAN7 - still no luck. same exact problem - traffic coming in and out, no internet connection available.

    it's already at 1500 by default, though...that's what it should be set at for cable.

    i've gone to the new office and tested it by rebooting the cable modem. no luck, at all.
     
  18. crackers8199

    crackers8199 LI Guru Member

    well, at least now we know the router 100% certainty is not defective...brought it home to test with my comcast home account, dynamic ip - works perfectly. something is messed up somewhere when i try to give it a static ip
     
  19. sterner

    sterner LI Guru Member

    What firmware is loaded? If not the newest, flash it with the latest.
     
  20. crackers8199

    crackers8199 LI Guru Member

    already did that...firmware is 2.0.17, which is the latest (feb 5 2007)
     
  21. sterner

    sterner LI Guru Member

    To better understand your setup, you are setting up the RV016 with IP 192.168.1.1, and the wireless as 192.168.1.2. The cable modem is plugged into WAN1 of the RV016 and is working in Gateway mode. The wireless is plugged into a LAN port on the RV016 as well as a LAN port on the wireless, and is set to Router mode. Is this correct so far?

    Also, are you using DHCP for clients, or static? If DHCP, use the RV016 for the DHCP server and disable it in the wireless.
     
  22. crackers8199

    crackers8199 LI Guru Member

    let me clarify - for right now, i have completely taken the WRT54G out of the equation. i'm trying to just get the rv016 working, and i can't even do that. NOTHING connected to the rv016 can see out to the internet when i'm using our static ip. if i let it get a dynamic ip, it works...as soon as i plug in the static ip info that comcast gave us, it goes kaput.
     
  23. Toxic

    Toxic Administrator Staff Member

    then obviously the info that you got from comcast is incorrect when using a static IP.
     
  24. crackers8199

    crackers8199 LI Guru Member

    but how is that possible when everything works fine using JUST the WRT54G as the gateway, and taking the rv016 out of the equation? using the exact same settings...
     
  25. Toxic

    Toxic Administrator Staff Member

    can you do me a favour a clone the mac address of the WRT54G's Mac Address onto the RV016 and see if that works.
     
  26. crackers8199

    crackers8199 LI Guru Member

    already did that, no luck.
     
  27. Toxic

    Toxic Administrator Staff Member

    and did you reboot the rv016 afterwards or release/renew dhcp?
     
  28. Toxic

    Toxic Administrator Staff Member

    The problem sounds like the CM is registered to the mac address of the WRT54G and this is why it works. The CM cannot re register a new mac address without a reboot. this is why you should clone the mac address. you are using the mac address of the WAN of the WRT54G?

    I can replicate this issue with my CM./ I cannot add a new router without rebooting the CM (and gettings a new IP address) or cloning the mac address of the last known mac address connected directly to the CM.
     
  29. crackers8199

    crackers8199 LI Guru Member

    i don't believe it's a mac address issue, and here's why - we have an older netgear router with a different mac address from the WRT54G. disconnected the WRT54G, plugged in the netgear - boom, instant internet connection. no problems whatsoever. if it were a mac address issue, wouldn't that get stuck too?

    plus, i've also tried this with our new cable modem at the new office, which doesn't know anything yet about any mac addresses...still won't work. it's like there's a route missing somewhere from the rv016's routing table - check out this tracert data:

    C:\>tracert 4.2.2.3

    Tracing route to 4.2.2.3 over a maximum of 30 hops

    1 1 ms 1 ms 1 ms 192.168.1.1
    2 192.168.1.1 reports: Destination host unreachable.

    Trace complete.

    Comcasts modems...be it their Motorola Surfboard, or the newer Arris MTA if you have their voice package, they memorize the MAC of the last device connected to it. If you quickly swap out another device (such as a new router)..the modem won't recognize the MAC..and will not give you a legit public IP address..you'll see a 192.168.100.xxx address instead.

    What you need to do is power off your modem for 5 minutes or so..(it will then "forget" the original MAC, then power it up with the new device (router) connected..and powered on. Then once the modem synchs up....power cycle your router again..and BAM...you'll be online.

    You do not need to call Comcast and have them do anything on their end unless you need a static IP address and have their static package..you'd then need to just have them bind that IP to your new MAC.

    WAN interface should be setup to "Obtain Auto"

    If you have an MTA from them, such as the Arris, you'll need to remove the battery pack inside when you power cycle it.

    I have Comcast at my home..I swap units often...very frequently..often several times a day as I'm trying new routers and linux distro routers and etc etc etc. And often do upgrades at clients that have Comcast.

    When connecting a wireless unit..you do not need to do any routing or set any routes, and it does not matter if the wireless unit is in router or gateway mode. You are connecting the wireless unit using it's LAN port...thus..you don't care if it's a wireless router set in gateway mode running NAT..traffic is not crossing over to it's WAN side. All you need to do is set it's LAN IP to be in the range of your primary router so you can manage it (just outside the DHCP pool of the primary router)...you need to disable DHCP on it, and you're done. Uplink with a LAN port of each.

    This is the Comcast gateway we have:

    http://www.smc.com/index.cfm?event=viewProduct&localeCode=EN_USA&cid=2&scid=20&pid=1611

    It's a modem/router combined into one. The Comcast rep said I didn't need to make any modifications to that, just to plug in my RV016 and insert settings that they gave me (static IP, subnet, gateway, DNS) and that the SMC-8014 would know how to handle it. I found that kind of odd, but who knows?

    Anyway, should I clone the RV016 MAC address to that of the SMC-8014?
     
  32. YeOldeStonecat

    YeOldeStonecat Network Guru Member

    Ahh...business account.

    Yeah...the one case with Comcast where you'll fill in static WAN IP info..the SMC will do IP mapping from the block of IPs you have. I have ..hmmm...3x clients with that setup.

    I did not need to do any MAC cloning...I never have done that with Comcast. Most cable ISPs in my area don't register MAC upsteam at the ISP..except those who do static business accounts via DHCP. (not Comcast)
     
  33. crackers8199

    crackers8199 LI Guru Member

    ...alright then, what exactly do I need to do to get this working? I haven't been able to pull it off yet.
     
  34. YeOldeStonecat

    YeOldeStonecat Network Guru Member

    Easiest thing...call Comcast support...tell them you need to use your own router..and have it take one of the public IP addresses. They will walk you through logging into the SMC...setting up something...and then you log into your own router...flip it's WAN interface to one of those static IP addresses (IP, subnet, remote gateway, DNS)...and you'll be done.

    I have the instructions for the SMC settings on my laptop..in my Jeep...don't have them handy right now. Comcasts support has always been great for me when I've called to do things like that.
     
  35. crackers8199

    crackers8199 LI Guru Member

    I'm a moron...LOL. Called Comcast tech support - the static IP wasn't on the modem yet. Tech logged into the modem, made some adjustments...boom, instant internet. Thanks to everyone for the help, and especially to YeOldeStonecat for telling me what should've been an obvious first step. :)
